A few things to note --
-- Andre Gurode didn't even finish among the top five NFC centers in the fan voting, and Jay Ratliff wasn't among the top five NFC defensive tackles. The players and coaches must have voted for them both overwhelmingly, because they're both starters.
-- Witten was fourth in the fan voting for NFC tight ends. Again, the players and coaches were the ones who made him a Pro Bowl starter.
-- McBriar was only third in the fan voting, so it was the players and coaches who put him in the game. He absolutely deserved it.
-- Several players won the fan voting at their position but didn't make the Pro Bowl: Bengals OT Andrew Whitworth, Browns OG Eric Steinbach, Packers OG Josh Sitton, Colts C Jeff Saturday, Commanders SS LaRon Landry and most of the special teamers (Akers and Hester are the only two who made it).
-- Along with Gurode and Ratliff, the players who weren't among the top five in the fan voting but will start in the Pro Bowl are Browns OT Joe Thomas, Panthers OT Jordan Gross, Chargers OG Kris Dielman, Patriots OG Logan Mankins, Falcons DE John Abraham, Titans KR Marc Mariani and Falcons special teamer Eric Weems.
-- Because of the way the NFL tabulates the voting, the fans' vote doesn't really count for one-third of the voting. It's actually just one of the three sources of votes.
